After years of drafts, revisions, and shifting timelines, the Cybersecurity Maturity Model Certification (CMMC) program is no longer just a concept. It's a contractual requirement, and enforcement begins soon. On September 9, 2025, the U.S. Department of Defense (DoD) released the final CMMC rule (48 CFR) for public inspection, with official publication in the Federal Register on September 10. From this point forward, all DoD contracts require some level of CMMC certification.
